The present invention is directed towards an electrocoating composition comprising a cyclic guanidine.

Electrodepositable coating composition containing a cyclic guanidine

Modified epoxy resins comprising the reaction product of a cycloaliphatic, polycyclic and/or aromatic biomass derived compound and an epoxy resin are disclosed. Aqueous dispersions and coatings comprising these reaction products are also disclosed.

Modified epoxy resins comprising the reaction product of a biomass derived compound and an epoxy resin, and aqueous dispersions and coatings comprising such resins

The present invention provides a film-forming composition. The composition includes a reaction product of:

Reaction product of polyamine, acyclic carbonate and cyclic carbonate

The invention provides a curable electrodepositable coating composition that has improved durability in the presence of metal ions. The coating composition includes one or more ungelled, active hydrogen-containing ionic salt group-containing resins which are electrodepositable on an electrode, one or more curing agents, and one or more metal deactivators.

Electrodepositable coating compositions and methods related thereto

Reaction product of polyamine and acyclic carbonate

The present invention is directed to electrodepositable coating compositions comprising an at least partially gelled resin or reaction product formed from reacting (i) an epoxy-functional polyester with (ii) an amine. The present invention also includes a method for electrocoating a conductive substrate with the described electrodepositable coating compositions. Additionally, the present invention is directed to a conductive substrate coated according to the described method.

Electrodepositable coating from gelled epoxy-polyester and amine

The present invention is directed to an electrodepositable composition of a resinous phase dispersed in an aqueous medium. The resinous phase includes an ionic polyester polymer prepared from a) an aromatic and/or cycloaliphatic carboxylic acid compound having at least two aromatic and/or secondary aliphatic carboxyl groups, b) a branched aliphatic, cycloaliphatic or araliphatic compound containing at least two aliphatic hydroxyl groups, the aliphatic hydroxyl groups being either secondary or tertiary hydroxyl groups or primary hydroxyl groups attached to a carbon adjacent to a tertiary or quaternary carbon, c) a compound including an ionic salt group or a group which is converted to an ionic salt group, and d) optionally, at least one hydroxyl substituted carboxylic compound comprising at least one tertiary aliphatic carboxyl group and at least two aliphatic hydroxyl groups. The present invention also includes a method for electrocoating a conductive substrate with the described electrodepositable composition. Lastly, the present invention is directed to a conductive substrate coated according to the described method.
